Rivea corymbosa (common synonym: Turbina corymbosa), is a species of morning glory plants, native throughout Latin America from Mexico in the North to Peru in the South and widely naturalised elsewhere. It is a perennial climbing vine with white flowers, often planted as an ornamental.
Known to natives of Mexico as Ololiuhqui (also spelled ololiuqui), its seeds, while little known outside of Mexico, were perhaps the most common hallucinogenic drug used by the natives.
The Nahuatl word ololiuhqui means "round thing," and refers to the small, brown, oval seeds of the morning glory, not the plant itself, which is called coaxihuitl, "snake-plant," in Nahuatl, and hiedra or bejicco in the Spanish language. The seeds, in Spanish, are sometimes called semilla de la Virgen (little seeds of the Virgin Mary).
The seeds are also used by Native curers in order to gain knowledge in curing practices and ritual, aswell as the causes for the illness.
Ololiuhqui (also spelled ololiuqui) is a hallucinogen, little known outside of Mexico, but perhaps the most common psychotropic drug used by the natives of that country.
In 1941, Richard Evans Schultes identified ololiuhqui as the seed of a species of morning glory, Rivea corymbosa.
The Nahuatl word ololiuhqui means "round thing," and refers to the small, brown, oval seeds of the morning glory, not the plant itself, which is called coaxihuitl, "snake-plant," in Nahuatl, and hiedra or bejicco in the Spanish language.
Ololiuhqui is the Aztec name for the seeds of certain climbing plants (Convolvulaceae) that, like the mescaline cactus peyotl and the teonanacatl mushrooms, were used in pre-Columbian times by the Aztecs and neighboring people in religious ceremonies and magical healing practices.
Ololiuhqui is still used even today by certain Indian tribes like the Zapotec, Chinantec, Mazatec, and Mixtec, who until a short time ago still led a geniunely isolated existence, little influenced by Christianity, in the remote mountains of southern Mexico.
Moreover, the psychic effects of ololiuhqui, in fact, differ from those of LSD in that the euphoric and the hallucinogenic components are less pronounced, while a sensation of mental emptiness, often anxiety and depression, predominates.
